Abstract: When a first type gear shift line is used as a gear shift line to change the gear ratio, and a predetermined condition including a condition that a state of charge of the power storage device is equal to or lower than a first ratio is satisfied, the control device changes the gear shift line to a second type gear shift line that recommends a lower speed gear ratio than the first type gear shift line.

Abstract: When the required driving force is larger than the first upper limit driving force, the control device sets a target compensation power of a power storage device, based on a difference between the required driving force and the first upper limit driving force. Further, the control device gradually increases a working compensation power toward the target compensation power when the gear ratio of the stepped transmission is changed, compared with an increase in the working compensation power when the gear ratio of the stepped transmission is not changed.

Abstract: While a vehicle is traveling in an automatic driving mode, an auto-driving oil pressure changing unit makes the engagement pressure of hydraulic oil supplied to a release-side engagement device to be released during a downshift of a stepwise shifting unit, higher than the engagement pressure set during traveling in a manual driving mode, so that retraction of the acceleration due to a drop of drive torque during the downshift is reduced. At this time, an auto-driving rotating machine controller makes drive-side MG2 torque generated from a second rotating machine, larger than that generated during traveling in the manual driving mode, so as to speed up the progress of the downshift, and prevent retraction of the acceleration from being prolonged.

Abstract: A control apparatus (80; 122) for a vehicle provided with a motor/generator (MG2; MG) functioning as a drive power source, and a step-variable transmission (20; 110) which constitutes a part of a power transmitting path between the drive power source and drive wheels (28; 116) and which is placed in a selected one of a plurality of speed positions with engagement of a selected one or ones of a plurality of coupling devices (CB). The control apparatus includes: a torque control portion (86) configured to control an output torque (Ti) of the drive power source (MG2) during a shifting action of the step-variable transmission (40; 110) from one of the speed positions to another of the speed positions, on the basis of a required vehicle drive torque (Tidem) corresponding to an operation amount (θacc) of an accelerator pedal, such that a value representing a state of a rotary motion of an input rotary member (30) of the step-variable transmission coincides with a target value; and a torque limiting portion (92) configured to limit the required vehicle drive torque to a predetermined lower limit value (Tif) in the process of a shift-up action of the step-variable transmission which is performed by placement of the accelerator pedal in an operated position.
